Objective-c – Apple Mach-O Linker Warning – Framework Search Paths

I've stumbled upon an annoying error: Apple Mach-O Linker Warning.

ld: warning: directory not found for option '-F/Users/erik/Documents/Xcode/Hello'

ld: warning: directory not found for option '-FFriend'.

My Project folder is called "Hello Friend".
In my Framework Search Paths it has 4 rows showing:

• $(inherited)
• /Users/erik/Documents/Xcode/Hello
• Friend
• $(PROJECT_DIR)

It looks like it has divided the word "Hello Friend" into two sections because of the space between the words so I'm thinking that's the explanation?

I've tried to edit it to

• $(inherited)
• /Users/erik/Documents/Xcode/Hello Friend
• $(PROJECT_DIR)

but it jumps back.

Any ideas?

Very much appreciated!
